Markaudio CHN-40P Full-range Woofer

The Markaudio CHN-40P Full-range Woofer represents a masterful blend of compact engineering and high-fidelity audio performance, designed to deliver clear, coherent sound across the frequency spectrum. As a broadband subwoofer, it excels in applications where space is at a premium yet audio quality cannot be compromised. This driver is ideally suited for DIY speaker projects, small bookshelf enclosures, and custom audio installations, making it a versatile choice for hobbyists and professionals alike who seek to achieve full-range reproduction without the need for multiple drivers.

Technically, the CHN-40P features a nominal diameter of 63.5mm and an 8-ohm impedance, ensuring compatibility with a wide range of amplifier designs. Its total Q factor (Qts) of 0.55, combined with a mechanical Q (Qms) of 2.9 and an electromagnetic Q (Qes) of 0.68, indicates a well-damped driver that offers controlled bass response and smooth integration into sealed or ported enclosures. The resonance frequency (Fs) of 107 Hz and a moving mass (Mms) of 1.39 grams contribute to its ability to produce articulate midrange and clear highs, while the low voice coil inductance (Le) of 0.065 mH ensures extended high-frequency extension. With a sensitivity of 85.93 dB (SPL 1m/2.83V) and a BL product of 3.06, this woofer delivers efficient, dynamic performance. Whether for a compact stereo system or a bespoke audio project, the CHN-40P offers a compelling solution for achieving full-range clarity in a small footprint.
